Configuring GPU Analysis

Click the New Analysis button on the VTune Amplifier toolbar.

The Analysis Type configuration window opens.

The right pane is updated with the configuration options for the selected analysis type. For GPU analysis, the VTune Amplifier provides three options: Analyze DirectX pipeline events, Analyze Processor Graphics hardware events, and Trace OpenCL kernels on Processor Graphics.

VTune Amplifier provides two presets of the hardware metrics. Both presets collect data about execution units (EUs) activity: EU Array Active, EU Array Stalled, EU Array Idle, Computing Threads Started, and Core Frequency.

• Overview event set also includes metrics that track general GPU memory accesses such as Memory Read/Write Bandwidth, GPU L3 Misses, Sampler Busy, Sampler Is Bottleneck, and GPU Memory Texture Read Bandwidth. These metrics can be useful for both graphics and compute-intensive applications.

• Global/local accesses event group also includes metrics that distinguish accessing different types of data on a GPU: Untyped Memory Read/Write Bandwidth, Typed Memory Read/Write Transactions, and SLM Read/Write Bandwidth. This metrics are useful for compute-intensive workloads on the GPU.
